Abstract: The invention pertains to a core-insertion device for a winding machine with at least one support or carrier drum (21, 22) for winding of web-like material (1) to be wound, in particular paper or the like, with a means for feeding cores (10) to a take-up position running approximately parallel to the at least one support or carrier drum(s) (21, 22), with a displacement means (2) for holding, in a detachable way, and displacing the core(s) (10) from the take-up position to a winding position located at the surface of the at least one support or carrier drum(s) (21, 22). The displacement means comprises, firstly, an elongated core carrier (3) having a pivot joint (6) arranged above its center of mass and core-holding means (30) in its lower region, and secondly, an element which can be moved between the take-up position and the winding position for a free-swinging accommodation of the elongated core carrier (3) at its pivot joint (6) and for displacing the core carrier (3) including at least one core (10) from the take-up position to the winding position. Due to the invention, it is possible merely to move the winding cores (10) itself, but not its receiving recess (11), from the take-up position to the winding position on a predetermined path and at an unchanging angle with respect to the core axis, deeply into the winding bed (23), and then to release them there only when the winding cores (10) have come into contact with the support drums (21, 22).

Patent CA-2264175-A1 (CA)
Title: Muting a microphone in radiocommunication systems
Inventor: ELOFSSON KJELL RICHARD
IPC: H04B1/40
Filed: 1997-08-22
Abstract: Comfort noise functions monitor background noise picked up by microphones in radiocommunication systems. These functions provide comfort noise information which is transmitted by remote units during periods of silence, so that the receiving party's equipment can output the proper background noise while the transmitting side can deactivate the transmitting circuitry to conserve power. Muting functions are accommodated by continuing to provide signals to the comfort noise functions so that the background noise is continuously monitored. When the muting mode of a remote unit is enabled, the transmitter receives comfort noise frames or silence frames instead of information output from a voice (speech) encoder.

Abstract: The invention concerns a stretcher comprising a carriage (21) subjected to a back-and-forward motion (2) for depositing in successive segments (2a ... 2d) a web of fibres (2) on an outgoing conveyor (6) moving along a direction (9). In order to produce ranges of different plies in the transverse profile of the lap (4) formed on the outgoing conveyor (6) by the web deposited in mutually overlapping segments, the points of inversion of direction (21) in the backward and forward motion of the carriage are different. As a result the successive folds (2ab, 2cd; 2bc, 2da) of the same direction are differently positioned, and the number of web plies in the lap is not the same over the whole width of the lap. The invention is useful for streamlining the lap freely and accurately.

Title: Application of a stabilized polymer gel to an alkaline treatment region for improved hydrocarbon recovery
Inventor: SYDANSK ROBERT D
IPC: C09K8/575
Filed: 1999-09-22
Abstract: A process is provided for reducing the permeability of or fluid mobility within a carbonate-containing treatment region in or proximate to a hydrocarbon-bearing formation below an earthen surface penetrated by a well bore. The process is initiated by preparing a gelation solution at the earthen surface which includes an acrylamide polymer, a crosslinking agent, a stabilizing agent and an aqueous solvent. The stabilizing agent is an acid additive, acidic pH buffer system, or delayed acid generator. The crosslinking agent is a chromium(III) complex having one or more chromium(III) cations and one or more carboxylate anions. The gelation solution is injected into the well bore and displaced into the treatment region where it is gelled in situ to form a gel which substantially reduces the permeability of or fluid mobility within the treatment region. The stabilizing agent maintains the stability of the gelation solution and resulting gel in situ by diminishing the detrimental effect of the alkaline carbonate minerals on the crosslinking agent.

The switch comprises a distributed distributed channel switch core, the core modules being respectively connected by a plurality of channels to a plurality of high-capacity packet switch edge modules. Each core module operates independently to schedule paths between edge modules, and reconfigures the paths in response to dynamic changes in data traffic loads reported by the edge modules. Reconfiguration timing between the packet switch modules and the channel switch core modules is performed to keep reconfiguration guard time minimized. The advantage is a high-capacity, load-adaptive, self-configuring switch that can be distributed to serve a large geographical area and can be scaled to hundreds of Tera bits per second to support applications that require very high bandwidth and a guaranteed quality of service.
